Creating a CPT (custom post type)

I have a plugin that I would like to migrate to MVC using this plugin.

I followed the instructions on the documentation to create a CPT but I’m not clear on how to show the DEFAULT TEMPLATE (admin area) that WordPress shows when a CPT is created.

Can you guide me with this please.

Here is the code in my old Plugin to create a CPT:

public function registrar_cpt_servicios()  {
		
		$servicio_labels = array(
			'name'               => _x( 'Servicios', 'post type general name', 'estilotu' ),
			'singular_name'      => _x( 'Servicio', 'post type singular name', 'estilotu' ),
			'menu_name'          => _x( 'Servicios', 'admin menu', 'estilotu' ),
			'name_admin_bar'     => _x( 'Servicio', 'add new on admin bar', 'estilotu' ),
			'add_new'            => _x( 'Nuevo servicio', 'book', 'estilotu' ),
			'add_new_item'       => __( 'Agregar nuevo servicio', 'estilotu' ),
			'new_item'           => __( 'Nuevo servicio', 'estilotu' ),
			'edit_item'          => __( 'Editar servicio', 'estilotu' ),
			'view_item'          => __( 'Ver servicios', 'estilotu' ),
			'all_items'          => __( 'Todos los Servicios', 'estilotu' ),
			'search_items'       => __( 'Buscar servicios', 'estilotu' ),
			'parent_item_colon'  => __( 'Servicios padres:', 'estilotu' ),
			'not_found'          => __( 'No se encontraron servicios.', 'estilotu' ),
			'not_found_in_trash' => __( 'No se encontraron servicios en la papelera.', 'estilotu' )
		);
		
		$args = array(
			'labels' 				=> $servicio_labels,
			'description' 			=> __( 'Servicios que ofrece un proveedor de Servicios.', 'estilotu' ),
			'public' 				=> true,
			'publicly_queryable'	=> true,
			'rewrite'            	=> array( 'slug' => 'servicios' ),
			'capability_type' 		=> 'post',
			'show_in_menu'       	=> true,
			'menu_position' 		=> 5,
			'hierarchical' 			=> false,
			'supports' 				=> array('title','editor','author','thumbnail','excerpt','comments','custom-fields'),
			'has_archive'			=> true,
			'capability_type' 		=> 'post'
			); 
		
		register_post_type('servicios', $args);
	}

Thanks
